The Object REXX programming language is an object-oriented scripting language initially produced by IBM for the operating system OS/2. It is a follow-on to and a significant extension of the "Classic Rexx" language originally created for the Conversational Monitor System (CMS) component of the operating system VM/SP and later ported to Multiple Virtual Storage (MVS), OS/2 and PC DOS. OS/2 version of IBM Object REXX is deeply integrated with IBM System Object Model (SOM).
On October 12, 2004, IBM released Object REXX as free and open-source software, giving rise to Open Object Rexx (ooREXX), now available for various operating systems: Linux, Solaris, Windows. This implementation includes a Windows Script Host (WSH) Scripting Engine for Rexx. The released sources however didn't include significant part of the SOM support.
